The discovery well was drilled in 1956 by the Arizona Exploration Company. Oil production is from two shallow marine sandstone bars formally called “transgressive Niobrara sandstones” (Molenaar, 1973). Fassett and Jentgen (1978) suggest Tocito Sandstone Lentil of the Mancos Shale (Upper Cretaceous) as a collective name for all of the lenticular “transgressive Niobrara sandstones.” Both sandstone bodies are closely associated with an unconformity that predates the Tocito, and locally displays erosional relief of as much as 150 ft in the underlying Carlile (Shale)-equivalent part of the Mancos Shale (McCubbin, 1969). Deposition of the sandstones took place during a net transgression of the Late Cretaceous sea. The oldest reservoir is between 25 and 30 ft thick and is nestled against an erosional outlier or cuesta located beneath the unconformity (Fig. 36). The trap is composed of shale and siltstone units of Carlile age in the Mancos Shale and thus is classified as a stratigraphic trap above an unconformity. The youngest reservoir at Horseshoe is between 30 and 45 ft thick and it changes laterally into a tight shallow marine sandstone unit which forms the trap (Fig. 36). This part of the field represents a facies-change trap. The depth to the producing units is about 1,200 ft.","PeriodicalId":260501,"journal":{"name":"The Last 10,000 Years","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116185208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
